[Differential diagnosis of coccidioidomycosis manifested by peripheral pulmonary lesion]. / Differentsial'naya diagnostika koktsidioidomikoza, manifestirovannogo perifericheskim obrazovaniem legkogo.

We present this clinical case as a demonstration of difficulties in differential diagnosis of pulmonary coccidioidomycosis. Differential diagnostics of peripheral pulmonary lesion performed using bronchoscopy with BAL and TBCB and video-assisted thoracic surgery (VATS) biopsy. Diagnostic specimens were tested using microbiological (luminescent microscopy, culture for M. tuberculosis (BACTEC MGIT960 and Lowenstein-Jensen Medium), RT-PCR, cytological and morphological (hematoxylin-eosin, Ziehl-Neelsen, PAS, Grocott methenamine silver (GMS) stainings) examinations. A diagnosis was verified correctly In Russia the country is not endemic for coccidioidomycosis and patient was treated accordingly. Diagnostics of peripheral pulmonary lesions requires of multidisciplinary approaches. Morphological examination, based on detection of only granulomatous inflammation in lung biopsy cannot be used for finally DS and requires microbiological confirmation for TB or other infections, and dynamic monitoring of the patient with concordance their anamnesis vitae and morbi.
